You would also have to provide a reverse mapping (a-la lcase) that let
you do this:

% ls foo*
foo^G^?bar
% rm foo^G^?bar

and have it work right.

The easy solution is to have this stuff active on line discipline 1 or
something (if your system is already using 1). The best way to do this
in general would be to have a couple of mapping tables (yes, in the tty
driver!) that allowed you to map arbitrary strings. I believe Microport
already does this...

How's this for a fantasy...

% stty -map lcase # clear lcase/ucase default map
% stty map cntrl # set control character map
% stty mapi '^[[K' '^U' # map CEOL to kill on input
% stty mapo '^U' '^M^[[K' # map kill character to CR plus erase line
% stty mapo '^H' '^H ^H' # map erase character to BS-space-BS

I'm sure we can beat the TOPS-20 terminal driver if we REALLY try :->.
